Robin Roberts, who overcame breast cancer five years ago, is battling another health scare. The “Good Morning America” anchor announced Monday that she has myelodysplastic syndrome, a disease of the blood and bone marrow, that was likely caused by her cancer treatment.
The 51-year-old anchor learned of the diagnosis on what was supposed to be a victorious day: when "GMA" beat NBC’s “Today” show in ratings for the first time in 16 years, she said in a statement on the network’s website: "Talk about your highs and lows!" Roberts said. She expects to undergo a bone marrow transplant this fall, with her sister as her donor.
